我台1984年引进鞍广产GSCT－1－Ⅱ型1kw单通道电视发射机。该发射机的中频调制部分经常发生故障。在图像调制器盘中，由于4个调制二极管特性不一致使得调制线性差。残余边带滤波器盘采用分立可调均电感电容元件较多，使得频带难于调整而且容易变化。伴音锁相电路容易失销，造成
I Taiwan in 1984 introduced a wide range of GSCT-1-Ⅱ 1kw single-channel television transmitter. The transmitter’s IF modulation section often fails. In the image modulator disk, the modulation linearity is poor due to the inconsistent characteristics of the four modulation diodes. Residual sideband filter plate with discrete inductors are more capacitive elements, making the band difficult to adjust and easy to change. Sound phase-locked circuit easily lost, caused
